Product Description

Noyes New OLS4 Light Source.

NOYES OLS4 ,from AFL and available in Canada from Simbol, is a hand-held, rugged, integrated two-port LED and LASER light source designed for performing insertion loss measurements on multimode or single-mode fiber optic links when used with an optical power meter. The LED and LASER outputs are stabilized to ensure accurate test results per current TIA/EIA requirements.

Equipped with industry standard 2 khz test tone, the OLS4 from AFL is an ideal tool to pair with an optical fiber identifier (OFI-200D) for use in fiber identification.
